(6•x) + 7 = 8
6x + 7 = 8
6x = 1
X = 1
Answer:
f ^-1 (x) =7X/5 - 2/5
Step-by-step explanation:
Answer:
(a) $180
(b) 25%
Step-by-step explanation:
(a) $126 = 30% of x; x is the total
so from this, you get an equation: 126 = 0.3x
solve the equation: x = 180; so the amount before
discount is $180
(b) You know the price of discount for the rice cooker is
180-126 which is $54
Then you subtract 54 from 64 to get the discount amount for the toaster
10/40 is 1/4 or 25%

We are asked to find the slope of the line that is parallel to the line
.

- Parallel lines have the same slope.
So let's first determine the slope of the first line, and then let's find the slope of the line that's parallel to it.

- The slope is the coefficient of x.
So the slope is
.
Can you guess the slope of the line that is parallel to the first line?
That's right! The slope is...

Hope it helps you out! :D
